GENERAL DESCRIPTION
The AD85631 is a precision instrumentation amplifier featuring low noise, rail-to-rail output and a power-saving shutdown mode. The AD8563 also features low offset voltage and drift coupled with high common-mode rejection. In shutdown mode, the total supply current is reduced to less than 4 μA. The AD8563 is capable of operating from 2.7 V to 5.5 V.

FEATURES
   Low offset voltage: 25 μV max
